Method of producing a crank arm for a crankshaft |
摘要 |
A method is provided for producing a crank arm for a crankshaft of an internal combustion engine, wherein the crankshaft is composed of separately produced parts. The crank arm is stamped out of a semifinished part and has a central recess for receiving a shaft journal of the crankshaft, and has an eccentrically disposed recess for receiving a crankshaft pin. A peripheral contour of the stamped part delimits a flywheel member of the crank arm. A recessed surface portion is formed or stamped in the crank arm in an area surrounding the central recess.
